Restrict number of sub childs(depth)

[asith-w]

Is there a method to prevent the generation of new child nodes after a certain depth, such as in the hierarchy: root -> child-child -> child -> child-child?
Alternatively, could users be restricted from creating new nodes by simply pressing and holding the 'tab' key?
(This is because having too many child nodes can make the mind map look confusing like this)

Like this

// ...
before: {
    insertSibling() {
      if(mei.currentNode.parent.children.length > 100)return false
      else return true
    },
}
// ...

Thank you very much for the quick reply

However, this it doesn't appear to function as expected. Is there a particular reason for this behavior?

Use 3.x if breaking changes don't affect you too much.
